I’m not willing to toss aside more than two years of training and investment based on three poor quarters in a Seattle road game in which no one played well.

Ahead of kickoff Sunday between the Dolphins and Seahawks, Bre Newcomer — who is engaged to Miami’s new QB1 — posted an Instagram snap from Lumen Field, where the former seventh-round pick will be under center as starting quarterback Tua Tagovailoa is currently sidelined following a scary concussion in Week 2.

Dolphins not quitting on Skylar Thompson, who will likely regain the backup quarterback job when his ribs heal.
